Chloroalkenes, important building blocks for cross-coupling reactions, are prepared in one step by the Suzuki reaction of 1,1-dichloroethylene and 1,2-dichloroethylene with alkenyl- and arylboronic acids. Under the proper reaction conditions, it is possible to obtain the monocoupling reaction to provide the corresponding chloroalkenes with good yields. This method represents an excellent route for
氯烯烃是交叉偶联反应的重要组成部分,可通过1,1-二氯乙烯和1,2-二氯乙烯与烯基和芳基硼酸的Suzuki反应一步制备。在适当的反应条件下,有可能获得单偶联反应,从而以良好的产率提供相应的氯代烯烃。该方法代表了从商购可得的原料制备氯代烯烃和氯二烯的绝佳途径。
